Open Meteo Weather Exploration

Background

Open-Meteo maintains an API for historical weather that allows for non-commercial usage of historical weather data maintained by the website.

This file builds on _v001, _v002, and _v003 to run exploratory analysis on some historical weather data.

Functions and Libraries

The exploration process uses tidyverse, ranger, several generic custom functions, and several functions specific to Open Meteo processing. First, tidyverse, ranger, and the generic functions are loaded:

In addition, pair plots by city are create for several combinations of variables:

keyVars <- c('pressure_msl', 
             'surface_pressure', 
             'soil_temperature_100_to_255cm',

        p1 <- allCity %>%
            mutate(across(c("pressure_msl", "surface_pressure", "soil_temperature_100_to_255cm"),

            scale_size_continuous("# Obs")
        print(p1)
    }
}

The cities are well differentiated by several combinations, particularly surface pressure vs. MSL pressure

A full random forest model is run for predicting city using LA, NYC, and Chicago:

## Warning: Dropped unused factor level(s) in dependent variable: Houston.

## 
## Accuracy of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 100%

Prediction accuracy is 100%, as expected given the significant differentiation. Houston is assessed for the city it is “most similar” to:

predictRF(rfCity$rf, df=allCity %>% filter(tt=="test", year==2022)) %>%
    plotConfusion(trueCol="fct_src", useSub=NULL, plotCont=FALSE)

Based on predictors in the three-city random forest, Houston is most similar to NYC. The full random forest model is updated, including Houston:

keyCities <- c("NYC", "LA", "Chicago", "Houston")
rfCity <- runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022, src %in% keyCities), 
                    yVar="fct_src", 
                    xVars=varsTrain, 
                    dfTest=allCity %>% filter(tt=="test", year==2022, src %in% keyCities), 
                    useLabel=keyLabel, 
                    useSub=stringr::str_to_sentence(keyLabel), 
                    returnData=TRUE
                    )

## 
## Accuracy of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 100%

Even with the similarities between NYC and Houston, there is sufficient differentiation in the predictors to drive 100% accuracy

A model is created to predict temperature for two cities:

keyCities <- c("NYC", "Chicago")
keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
rfTemp2m <- runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022, src %in% keyCities), 
                      yVar="temperature_2m", 
                      xVars=c(varsTrain[!str_detect(varsTrain, "^temp|ature$")]), 
                      dfTest=allCity %>% filter(tt=="test", year==2022, src %in% keyCities), 
                      useLabel=keyLabel, 
                      useSub=stringr::str_to_sentence(keyLabel), 
                      isContVar=TRUE,
                      rndTo=-1L,
                      refXY=TRUE,
                      returnData=TRUE
                      )

## Growing trees.. Progress: 65%. Estimated remaining time: 16 seconds.

## 
## R-squared of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 99.41% (RMSE 0.86 vs. 11.16 null)

## `geom_smooth()` using formula = 'y ~ x'

Temperature predictions on holdout data for NYC and Chicago have R-squared over 99%. The model is applied to data from Houston and LA:

# Temperature predictions for LA
predTempLA <- predictRF(rfTemp2m$rf, df=allCity %>% filter(tt=="test", year==2022, src=="LA"))
reportAccuracy(predTempLA, trueCol="temperature_2m", reportR2=TRUE, useLabel="LA temperature predictions")

## 
## R-squared of LA temperature predictions is: 92.38% (RMSE 1.89 vs. 6.86 null)

plotConfusion(predTempLA, trueCol="temperature_2m", plotCont=TRUE, rndTo=0.5, refXY=TRUE, useSub="LA")

## `geom_smooth()` using formula = 'y ~ x'

# Temperature predictions for Houston
predTempHOU <- predictRF(rfTemp2m$rf, df=allCity %>% filter(tt=="test", year==2022, src=="Houston"))
reportAccuracy(predTempHOU, trueCol="temperature_2m", reportR2=TRUE, useLabel="Houston temperature predictions")

## 
## R-squared of Houston temperature predictions is: 97.22% (RMSE 1.44 vs. 8.63 null)

plotConfusion(predTempHOU, trueCol="temperature_2m", plotCont=TRUE, rndTo=0.5, refXY=TRUE, useSub="Houston")

## `geom_smooth()` using formula = 'y ~ x'

Predictions for two cities not included in the original model have ~95% R-squared. Houston being relatively similar to NYC has higher R-squared than LA

Updated function runFullRF() is tested on LA and Houston:

# Temperature predictions for LA
runFullRF(yVar="temperature_2m", 
          useExistingRF=rfTemp2m$rf,

          )

## 
## R-squared of LA temperature predictions is: 92.382% (RMSE 1.89 vs. 6.86 null)

# Temperature predictions for Houston
runFullRF(yVar="temperature_2m",

## 
## R-squared of Houston temperature predictions is: 97.223% (RMSE 1.44 vs. 8.63 null)

The linear model is generally very accurate for Houston, with the exception of under-predicting the very highest temperatures. RMSE of temperature predictions is lowered to ~1 from ~1.5 observed using the random forest

Predictions are also explored in Los Angeles:

The linear model is generally inaccurate for LA, consistently underestimating temperatures. RMSE of temperature predictions is raised to ~4 from ~2 observed using the random forest

Los Angeles is meaningfully different from NYC and Chicago on key predictors:

Los Angeles is routinely hot and arid, while the other cities tend to be humid when they are hot. Data for an additional low-humidity city are downloaded, cached to avoid multiple hits to the server:

Distributions of several key variables are explored:

keyVars <- c('temperature_2m', 
             'relativehumidity_2m',

             )

allCity %>%

Las Vegas stands out for especially low relative humidity (even relative to LA), as well as dry soil (similar to LA)

The scatter of temperature and dewpoint is also explored:

allCity %>% 
    select(t=temperature_2m, d=dewpoint_2m, src) %>% 
    mutate(across(.cols=where(is.numeric), .fns=function(x) round(x))) %>% 
    count(src, t, d) %>%

    labs(x="Temperature (C)", y="Dewpoint (C)", title="Temperature vs. Dewpoint", subtitle="Hourly") + 
    scale_color_discrete(NULL) + 
    scale_size_continuous("# Obs")

## `geom_smooth()` using formula = 'y ~ x'

allCity %>% 
    group_by(src) %>%
    summarize(cor_td=cor(temperature_2m, dewpoint_2m))

## # A tibble: 5 × 2

## 2 Houston  0.834
## 3 LA       0.273
## 4 NYC      0.919
## 5 Vegas    0.371

Las Vegas is similar to LA, with lower dewpoints. The more humid cities have 80%+ correlation between temperature and dewpoint, dropping to ~40% correlation in the drier cities

Models for predicting city (one with soil temperature, one without) are saved using data without Las Vegas, for application to the new Las Vegas data:

The previously trained random forest models overwhelmingly predict Las Vegas as Los Angeles (if soil moisture is included) or Houston (if soil moisture is excluded)

The linear approximation for estimating temperature based on dewpoint and relative humidity is applied:

The linear approximation based on dewpoint and relative humidity is inaccurate for predicting temperatures in Las Vegas, consistent with Las Vegas having T/D trends very different from originally modeled cities, NYC and Chicago

Las Vegas is meaningfully different from NYC and Chicago on key predictors:

tmpPlotData <- allCity %>% 
    select(src, relativehumidity_2m, dewpoint_2m, temperature_2m) %>% 
    mutate(across(where(is.numeric), .fns=round)) %>% 
    count(src, relativehumidity_2m, dewpoint_2m, temperature_2m)

tmpPlotData %>%
    count(src, temperature_2m, dewpoint_2m, wt=n) %>%
    ggplot(aes(x=temperature_2m, y=dewpoint_2m)) + 
    geom_point(aes(color=src, size=n), alpha=0.2) + 
    geom_smooth(aes(color=src, weight=n), method="lm") +
    labs(title="T/D by city")

## `geom_smooth()` using formula = 'y ~ x'

tmpPlotData %>%
    count(src, temperature_2m, relativehumidity_2m, wt=n) %>%
    ggplot(aes(x=temperature_2m, y=relativehumidity_2m)) + 
    geom_point(aes(color=src, size=n), alpha=0.1) + 
    geom_smooth(aes(color=src, weight=n), method="lm") +
    labs(title="T/RH by city")

## `geom_smooth()` using formula = 'y ~ x'

The existing random forest model, trained on NYC and Chicago, is also tested on Las Vegas temperatures:

# Temperature predictions for Vegas
runFullRF(yVar="temperature_2m", 
          useExistingRF=rfTemp2m$rf, 
          dfTest=allCity %>% filter(tt=="test", year==2022, src=="Vegas"), 
          useLabel="Las Vegas temperature predictions", 
          useSub="Las Vegas", 
          isContVar=TRUE,
          rndTo=0.5, 
          refXY=TRUE
          )

## 
## R-squared of Las Vegas temperature predictions is: 90.29% (RMSE 3.32 vs. 10.65 null)

## `geom_smooth()` using formula = 'y ~ x'

The random forest is more accurate than the linear model in predicting temperatures in Las Vegas based on training data from other cities. RMSE is ~3 rather than the ~10 from the linear model application

All combinations of two variables are explored for predicting temperature on a smaller training dataset:

# Train and test data
dfTrainTemp <- allCity %>% 
    filter(!(src %in% c("Vegas")), tt=="train", year<2022) %>% 
    mutate(fct_src=factor(src))
dfTestTemp <- allCity %>%

    mutate(fct_src=factor(src))

                                 yVar="temperature_2m", 
                                 xVars=possTempVars[c(idx1, idx2)],

Chicago and NYC are both very well-represented by the training data, while a majority of Las Vegas observations are largely or entirely absent from the training data

There are strong relationships among dewpoint, vapor pressure deficit, relative humidity, and temperature:

dfTestTemp_v2 %>% 
    select(src, vapor_pressure_deficit, dewpoint_2m, temperature_2m, relativehumidity_2m) %>% 
    mutate(across(c(dewpoint_2m, temperature_2m, relativehumidity_2m), .fns=function(x) round(x))) %>% 
    filter(dewpoint_2m %in% c(-10, 0, 10, 20)) %>% 
    ggplot(aes(x=vapor_pressure_deficit, y=temperature_2m)) + 
    geom_point(aes(color=factor(dewpoint_2m))) + 
    scale_color_discrete("Dewpoint")

dfTestTemp_v2 %>% 
    select(src, vapor_pressure_deficit, dewpoint_2m, temperature_2m, relativehumidity_2m) %>% 
    mutate(across(c(dewpoint_2m, temperature_2m, relativehumidity_2m), .fns=function(x) round(x))) %>% 
    filter(dewpoint_2m %in% c(-10, 0, 10, 20)) %>% 
    ggplot(aes(x=relativehumidity_2m, y=temperature_2m)) + 
    geom_point(aes(color=factor(dewpoint_2m))) + 
    scale_color_discrete("Dewpoint")

To better cover the predictor space, a model using only dewpoint and vapor pressure deficit is run on NYC and Vegas, then applied to the others:

# Train and test data
dfTrainTemp_v3 <- allCity %>% 
    filter(src %in% c("NYC", "Vegas"), tt=="train", year<2022) %>%

dfTestTemp_v3 <- allCity %>%

The model trained on NYC and Vegas generally performs very well on all cities

An approximate formula for relative humidity is assessed for resonance with the data:

calcRH <- function(t, d, c1=17.63, c2=243) {

## `geom_smooth()` using formula = 'y ~ x'

The formula is an exact match to the reported data, allowing the random forest to find the correct third value when given two of T, D, RH, provided that the training space also includes that combination

Example training data is created for all temperatures and dew points between -30 and 50 (rounded to the nearest 1), with RH calculated based on formula:

Training data rounds temperature to the nearest degree and RH always rounds to the nearest percent, making temperature predictions commonly off by a fraction of a degree. The model is generally accurate, with the exception of very low relative humidities (rounding is much more impactful) and very high relative humidities (mtry=1 creates challenges since grid-based training data overweights some T/D combinations).

The example training data is modified to be more consistent with T/D typically observed:

The weighted training data performs slightly better for data points with high density, at the offset of somewhat worse performance for less commonly observed relative humidities

Example training data is expanded all temperatures and dew points between -50 and 50 (rounded to the nearest 1), with RH calculated based on formula:

The expanded training data improves prediction quality at very low temperatures. Predictions continue to be less accurate at very low, and very high, relative humidities

Rounding is a meaningful challenge for some temperature predictions given training data that rounds temperature and dewpoint to the nearest 1:

As temperature and dewpoint converge (high relative humidity), the same rounded value of temperature can occur with RH that spans as much as ~4%. Greater granularity in the training data may help address this. As relative humidity gets very low, a given dewpoint can be associated with over 5 degrees of temperature variation for the same rounded value of RH. Since the raw data has rounded RH, this may be a harder constraint, though extremely low relative humidity is uncommon so this may not be a major driver of overall RMSE

Training data is updated to include 0.2 degree granularity for temperature and dewpoint:

The model is now accurate even at high relative humidities

An approximate formula for vapor pressure deficit is assessed for resonance with the data:

# Approximate formula for vapor pressure deficit
# Source https://pulsegrow.com/blogs/learn/vpd
calcVPD <- function(t, d, c1=610.78, c2=17.2694, c3=237.3) {
    # SVP (saturation vapor pressure) = 610.78 * exp(T * 17.2694 / (T + 237.3))
    # VPD = (1 - RH/100) * SVP
    # Formula produces VPD in Pa, divide by 1000 to convert to kPa
    (1 - calcRH(t, d)/100) * c1 * exp(t * c2 / (t + c3)) / 1000
}

# Applied to sample data
dfTestTemp_v3 %>%
    select(src, t=temperature_2m, d=dewpoint_2m, v=vapor_pressure_deficit) %>%
    mutate(cvpd=calcVPD(t, d)) %>%
    ggplot(aes(x=v, y=cvpd)) + 
    geom_point(aes(color=src)) + 
    facet_wrap(~src) + 
    geom_smooth(method="lm") + 
    geom_abline(intercept=0, slope=1, lty=2) + 
    labs(x="Reported vapor pressure deficit (kPa)", 
         y="Formula vapor pressure deficit (kPa)", 
         title="Vapor pressure deficit by formula from temperature and dewpoint vs. reported in raw data") + 
    scale_color_discrete(NULL)

## `geom_smooth()` using formula = 'y ~ x'

The formula is a strong match to the reported data, which should allow the random forest to find the correct third value when given two of T, D, VPD (provided that training space also includes that combination)

Example training data is created for all temperatures and dew points between -50 and 50 (rounded to the nearest 1), with VPD calculated based on formula:

Training data rounds temperature to the nearest degree, making temperature predictions commonly off by a fraction of a degree. The model is generally accurate, with the exception of very low/high vapor pressure deficits.

The model is effective at predicting cloud cover. Of interest, variable importance is highest for ‘weathercode’, a categorical variable improperly run as an integer. The interpretation of WMO weather codes is available at https://www.nodc.noaa.gov/archive/arc0021/0002199/1.1/data/0-data/HTML/WMO-CODE/WMO4677.HTM

The weather code and cloud cover variables are explored:

# Distribution of 'cloudcover'
allCity %>% 
    select(weathercode, cloudcover) %>% 
    mutate(weathercode=factor(weathercode)) %>% 
    ggplot(aes(x=cloudcover)) + 
    geom_histogram(bins=50, aes(y=after_stat(count)/sum(after_stat(count)))) + 
    labs(title="Distribution of cloud cover", y="Proportion of total observations")

# Distribution of 'weathercode'
allCity %>% 
    select(weathercode, cloudcover) %>% 
    mutate(weathercode=factor(weathercode)) %>% 
    ggplot(aes(x=weathercode)) + 
    geom_bar(aes(y=after_stat(count)/sum(after_stat(count)))) + 
    labs(title="Distribution of weather code", y="Proportion of total observations")

# Cloud cover boxplot by weather code
allCity %>% 
    select(weathercode, cloudcover) %>% 
    mutate(weathercode=factor(weathercode)) %>% 
    ggplot(aes(x=weathercode, y=cloudcover)) + 
    geom_boxplot(fill="lightblue") + 
    labs(title="Cloud cover by weather code", y="Cloud cover")

Weather code is strongly predictive of cloud cover, with codes 00 and 01 associated with few clouds and other clouds associated with many clouds

The model is run to predict cloud cover using only weather code as a factor:

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
runFullRF(dfTrain=allCity %>% mutate(fct_wmo=factor(weathercode)) %>% filter(tt=="train", year<2022), 
          yVar="cloudcover", 
          xVars=c("fct_wmo"), 
          dfTest=allCity %>% mutate(fct_wmo=factor(weathercode)) %>% filter(tt=="test", year==2022), 
          useLabel=keyLabel, 
          useSub=stringr::str_to_sentence(keyLabel), 
          isContVar=TRUE,
          rndTo=-1L,
          refXY=TRUE,
          returnData=FALSE
          )

## 
## R-squared of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 92.458% (RMSE 9.96 vs. 36.27 null)

## `geom_smooth()` using formula = 'y ~ x'

The model drives over 90% R-squared, with RMSE falling from ~35 in the baseline to ~10 with predictions based solely on weather code

The model is run to predict cloud cover using only the three cloud cover (low, mid, high) predictors:

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
runFullRF(dfTrain=allCity %>% mutate(fct_wmo=factor(weathercode)) %>% filter(tt=="train", year<2022), 
          yVar="cloudcover", 
          xVars=c(varsTrain[str_detect(varsTrain, pattern="cloudcover_")]), 
          dfTest=allCity %>% mutate(fct_wmo=factor(weathercode)) %>% filter(tt=="test", year==2022), 
          useLabel=keyLabel, 
          useSub=stringr::str_to_sentence(keyLabel), 
          isContVar=TRUE,
          rndTo=-1L,
          refXY=TRUE,
          returnData=FALSE
          )

## 
## R-squared of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 99.129% (RMSE 3.39 vs. 36.27 null)

## `geom_smooth()` using formula = 'y ~ x'

The model drives over 99% R-squared, with RMSE falling from ~35 in the baseline to ~3 with predictions based solely on cloud cover sub-types

All combinations of two variables are explored for predicting cloud cover on a smaller training dataset:

# Train and test data
dfTrainCloud <- allCity %>% 
    filter(tt=="train", year<2022) %>% 
    mutate(fct_src=factor(src))
dfTestCloud <- allCity %>% 
    filter(tt=="test", year==2022) %>% 
    mutate(fct_src=factor(src))

# Variables to explore
possCloudVars <- c(varsTrain[!str_detect(varsTrain, "cover$")], "month", "tod")

# Subsets to use
set.seed(24080616)
idxSmallCloud <- sample(1:nrow(dfTrainCloud), 5000, replace=FALSE)
mtxSmallCloud <- matrix(nrow=0, ncol=3)

    for(idx2 in (idx1+1):length(possCloudVars)) {
        r2SmallCloud <- runFullRF(dfTrain=dfTrainCloud[idxSmallCloud,], 
                                  yVar="cloudcover",

The random forest model is re-run to predict rain, using only precipitation and snowfall as predictors:

The random forest model is similarly effective at predicting rain using precipitation and snowfall

All combinations of two variables are explored for predicting rain on a smaller training dataset:

# Train and test data created previously (dfTrainCloud and dfTestCloud)
# Variables to explore
possRainVars <- c(varsTrain[!str_detect(varsTrain, "rain")], "month", "tod")

# Subsets to use
set.seed(24081818)

In contrast to previous models, R2 for predicting rain is significantly improved by access to a much larger training dataset

A model is run to predict snowfall, at first allowing precipitation and rain as predictors:

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
rfSnowFull <- runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022), 
                        yVar="snowfall", 
                        xVars=c(varsTrain[!str_detect(varsTrain, "^snowfall$")]), 
                        dfTest=allCity %>% filter(tt=="test", year==2022), 
                        useLabel=keyLabel, 
                        useSub=stringr::str_to_sentence(keyLabel), 
                        isContVar=TRUE,
                        rndTo=-1L,
                        refXY=TRUE,
                        returnData=TRUE
                        )

## Growing trees.. Progress: 41%. Estimated remaining time: 43 seconds.
## Growing trees.. Progress: 80%. Estimated remaining time: 15 seconds.

## 
## R-squared of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 94.034% (RMSE 0.01 vs. 0.04 null)

## `geom_smooth()` using formula = 'y ~ x'

The model is reasonably effective at predicting snowfall, primarily by leveraging highly associated predictors precipitation and weather code. The model generally under-predicts high rainfall observations

A similar process is run using the linear model:

# Eliminate diffuse radiation due to rank-deficiency
lmSnowFull <- lm(snowfall ~ ., 
                 data=allCity %>% 
                     filter(tt=="train", year<2022) %>% 
                     mutate(weathercode=factor(weathercode)) %>%
                     select(all_of(varsTrain)) %>% 
                     select(-diffuse_radiation)
                 )
summary(lmSnowFull)

## 
## Call:
## lm(formula = snowfall ~ ., data = allCity %>% filter(tt == "train",

Even with many confounders, the linear model largely identifies that precipitation and rain predict snowfall. As well, the linear model identifies weather codes 71, 73, and 75 which each mean that snow is falling

The linear model has very strong explanatory and predictive power. Snowfall (cm) appears defined in the raw data as 7 * (precipitation (mm) minus rain (mm)):

allCity %>%

         x=NULL, 
         y="Snowfall (cm) divided by\n(0.7 * precipitation (mm))"
         )

While rain is sometimes falling during snow events, in general the precipitation falls mainly or enitrely as snow during weathercode 71, 73, and 75. There is no snowfall under other weathercode

A model is run to predict weathercode, at first allowing precipitation, rain, and snowfall as predictors:

## Accuracy of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 99.634%

Accuracy is extremely high, with weathercode being strongly linked to cloud cover, precipitation rate, and percentage of precipitation falling as snow

Relationships between precipitation, rain, snow, clouds, and weathercode are further explored:

Not surprisingly, the random forest is effective at pulling apart very clean data splits like these

A model is run to predict weathercode, using only cloud cover, precipitation, rain, and snowfall as predictors, and with random forest defaults (mtry=2 for 4 predictors):

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022) %>% mutate(weathercode=factor(weathercode)), 
          yVar="weathercode", 
          xVars=c("cloudcover", "precipitation", "rain", "snowfall"), 
          dfTest=allCity %>% filter(tt=="test", year==2022) %>% mutate(weathercode=factor(weathercode)), 
          useLabel=keyLabel, 
          useSub=stringr::str_to_sentence(keyLabel), 
          isContVar=FALSE,
          rndTo=-1L,
          refXY=TRUE,
          returnData=FALSE
          )

## 
## Accuracy of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 99.436%

Accuracy remains over 99%, with main errors being cloudiness classification when there is zero precipitation

The model is updated using mtry=4 and mtry=1:

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022) %>% mutate(weathercode=factor(weathercode)), 
          yVar="weathercode", 
          xVars=c("cloudcover", "precipitation", "rain", "snowfall"), 
          dfTest=allCity %>% filter(tt=="test", year==2022) %>% mutate(weathercode=factor(weathercode)), 
          useLabel=keyLabel, 
          useSub=stringr::str_to_sentence(keyLabel), 
          isContVar=FALSE,

          )

## 
## Accuracy of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 99.429%

The model performs with much lower accuracy for mtry=1 rather than mtry=2, but accuracy is essentially identical (over 99%) for mtry=2 and mtry=4. The main issue with mtry=1 is inability to classify non-precipitation days since snowfall, rain, and precipitation as stand-alones do not distinguish degree of cloudiness

All combinations of two variables are explored for predicting weathercode on a smaller training dataset:

# Train and test data created previously (dfTrainCloud and dfTestCloud)
# Variables to explore
possWCVars <- c(varsTrain[!str_detect(varsTrain, "weathercode")], "month", "tod")

# Subsets to use
set.seed(24083015)
idxSmallWC <- sample(1:nrow(dfTrainCloud), 5000, replace=FALSE)
mtxSmallWC <- matrix(nrow=0, ncol=3)

for(idx1 in 1:(length(possWCVars)-1)) {
    for(idx2 in (idx1+1):length(possWCVars)) {
        r2SmallWC <- runFullRF(dfTrain=dfTrainCloud[idxSmallWC,] %>% mutate(weathercode=factor(weathercode)), 
                               yVar="weathercode", 
                               xVars=possWCVars[c(idx1, idx2)], 
                               dfTest=dfTestCloud %>% mutate(weathercode=factor(weathercode)),

                               makePlots=FALSE,
                               returnData=TRUE
                               )[["rfAcc"]]

Even with many confounders, the linear model largely identifies that high-level wind-speed is a strong predictor for ground-level wind speed. Many other variables have statistically significant impact also, with wind gusts, apparent temperature, and actual temperature being of interest

The model is re-run using only the best four predictors:

# Best predictors only

The four-predictor model retains most, but not all, of the explanatory power of the full model. R2 on the test dataset falls from ~94% to ~92% (RMSE increases from ~1.9 to ~2.2)

Each of the best-four predictors is run individually, with metrics assessed on training data:

sapply(c("windspeed_100m", "windgusts_10m", "apparent_temperature", "temperature_2m"), 
       FUN=function(x) summary(lm(windspeed_10m ~ get(x), data=allCity))[c("sigma", "r.squared")] %>% unlist
       ) %>%
    t()

## windspeed_100m       2.389386 0.88251896
## windgusts_10m        3.427561 0.75825046
## apparent_temperature 6.835019 0.03866518
## temperature_2m       6.916588 0.01558339

High-level wind speed and wind gusts have good standalone predictive power on ground level wind speed. Temperature and apparent temperature have essentially no standalone predictive power on ground level wind speed

Each variable is run through the random forest standalone, using a smaller training dataset:

The random forest model identifies the same standalone best predictors, and with very similar R2

A null model is run to predict ground-level wind speed, using only city, month, and day/night (mtry=3):

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
rfWindNull <- runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022), 
                      yVar="windspeed_10m", 
                      xVars=c("src", "month", "tod"), 
                      dfTest=allCity %>% filter(tt=="test", year==2022), 
                      useLabel=keyLabel, 
                      useSub=stringr::str_to_sentence(keyLabel), 
                      mtry=3,
                      isContVar=TRUE,
                      rndTo=-1L,
                      refXY=TRUE,
                      returnData=TRUE
                      )

## Growing trees.. Progress: 74%. Estimated remaining time: 10 seconds.

## 
## R-squared of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 25.22% (RMSE 6.56 vs. 7.58 null)

## `geom_smooth()` using formula = 'y ~ x'

The null model is minimally effective (~25% R-squared) at predicting ground-level wind speed

The same null model is run using lm:

# Null predictors only
lmWindNull <- lm(windspeed_10m ~ src:month:tod + 0, 
                 data=allCity %>% 
                     filter(tt=="train", year<2022)
                 )
summary(lmWindNull)

As expected, the models drive nearly identical results and R-squared

A model is run to predict ground-level wind speed, excluding high-level wind speed and gusts as predictors:

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022), 
          yVar="windspeed_10m", 
          xVars=c(varsTrain[!str_detect(varsTrain, "^wind[sg]")], "src", "month", "tod"), 
          dfTest=allCity %>% filter(tt=="test", year==2022), 
          useLabel=keyLabel, 
          useSub=stringr::str_to_sentence(keyLabel), 
          isContVar=TRUE,
          rndTo=-1L,
          refXY=TRUE,
          returnData=FALSE
          )

## R-squared of predictions based on pre-2022 training data applied to 2022 holdout dataset is: 70.684% (RMSE 4.11 vs. 7.58 null)

## `geom_smooth()` using formula = 'y ~ x'

The model is reasonably effective (~70% R-squared) at predicting ground-level wind speed, by leveraging multiple predictors in combination

The linear model is re-run for ground wind speed, excluding wind gusts and high-level wind speed:

The model is highly effective at predicting evapotranspiration, primarily by using radiation variables

The linear model is run for evapotranspiration, using all predictors:

# Eliminate diffuse radiation due to rank-deficiency

Even with many confounders, the linear model largely identifies that radiation is a strong predictor for evapotranspiration. The random forest drives higher R-squared and improved RMSE (RMSE 0.01 RF vs. 0.04 linear)

Correlations between predictors and evapotranspiration are assessed:

## `geom_smooth()` using formula = 'y ~ x'

The model is highly effective at predicting relative humidity, primarily by using vapor pressure deficit. There is a mathematical formula that maps T, D to either RH or VPD, and it is notable that the initial model places more emphasis on the derived predictor (VPD) rather than the two base predictors (T, D)

The linear model is run for relative humidity, using all predictors:

# Eliminate diffuse radiation due to rank-deficiency
lmRHFull <- lm(relativehumidity_2m ~ ., 
               data=allCity %>% 
                   filter(tt=="train", year<2022) %>%

The linear model prefers dewpoint and temperature to VPD as predictors for relative humidity. The linear model drives lower R-squared and increased RMSE (RMSE ~1.9 RF vs. ~6.8 linear)

Surface pressure appears to be a Simpson’s paradox, with an overall increasing relationship to relative humidity but a generally decreasing relationship when controlled for city. The other plotted predictors have similar trends by individual city and overall

A model using surface pressure only is run, then a model that adds city:

keyLabel <- "predictions based on pre-2022 training data applied to 2022 holdout dataset"
runFullRF(dfTrain=allCity %>% filter(tt=="train", year<2022), 
          yVar="relativehumidity_2m",

Adding city to the surface pressure model only modestly improves predictive power

The linear model is re-run for relative humidity, using only surface pressure and city:

Distributions of several key variables are explored:

keyVars <- c('temperature_2m', 
             'relativehumidity_2m', 
             'dewpoint_2m', 
             'shortwave_radiation',

             'soil_moisture_28_to_100cm', 
             'soil_moisture_100_to_255cm'
             )

allCity %>%
    colSelector(vecSelect=c("src", keyVars)) %>%
    pivot_longer(cols=-c(src)) %>%
    ggplot(aes(x=src, y=value)) + 
    geom_boxplot(aes(fill=src)) + 
    facet_wrap(~name, scales="free_y") + 
    labs(x=NULL, y=NULL, title="Distribution of Key Metrics by City") + 
    scale_fill_discrete(NULL)

At a glance, Miami seems similar to Houston on several metrics. The scatter of temperature and dewpoint is also explored:

allCity %>% 
    select(t=temperature_2m, d=dewpoint_2m, src) %>% 
    mutate(across(.cols=where(is.numeric), .fns=function(x) round(x))) %>% 
    count(src, t, d) %>% 
    ggplot(aes(x=t, y=d)) + 
    geom_point(aes(size=n, color=src), alpha=0.1) + 
    geom_smooth(aes(color=src, weight=n), method="lm") +
    labs(x="Temperature (C)", y="Dewpoint (C)", title="Temperature vs. Dewpoint", subtitle="Hourly") + 
    scale_color_discrete(NULL) + 
    scale_size_continuous("# Obs")

## `geom_smooth()` using formula = 'y ~ x'

allCity %>% 
    group_by(src) %>%
    summarize(cor_td=cor(temperature_2m, dewpoint_2m))

## # A tibble: 6 × 2
##   src     cor_td
##   <chr>    <dbl>
## 1 Chicago  0.950
## 2 Houston  0.834
## 3 LA       0.273
## 4 Miami    0.792
## 5 NYC      0.919
## 6 Vegas    0.371

Miami exhibits strong correlation between temperature and dewpoint, most similar in magnitude to Houston

A basic rpart model is run excluding Miami, with predictions made on holdout data including Miami:

A basic tree model works well to split the data by city, and almost always predicts Miami as LA when trained without Miami data
